Instituut voor de Nederlandse Listed by thegentlemen Ransomware Group

On May 14, 2026, the Dutch language institute Instituut voor de Nederlandse Taal appeared on the leak site of the ransomware group known as The Gentlemen. Internal files were allegedly exfiltrated during a ransomware attack, exposing data that could affect researchers, staff, partners, and anyone whose information was stored in the institute’s systems.

What's Publicly Reported from Reporting

Public reporting indicates the institute, which maintains authoritative Dutch language resources including the Algemene Nederlandse Spraakkunst, had internal files stolen. The data was later listed on the group’s leak portal hosted via ransomware.live. No exact victim count has been disclosed, and the precise volume or sensitivity of the files remains unclear from available reporting. The breach follows the group’s typical pattern of exfiltrating data before demanding payment to prevent publication.

Why This Matters for You and Your Family

When an organization that holds personal or professional records suffers a breach, the information can spread far beyond its walls. If you have corresponded with the institute, contributed to its research, or had your name, email, or contact details appear in its files, that data may now be in the hands of criminals. For ordinary people and families, this often leads to follow-on scams, phishing attempts, or identity theft that can affect bank accounts, government services, or children’s online profiles. Credential leaks like this one frequently cascade into account takeovers across unrelated services where the same email and password are reused.

The Doxxing and Identity-Chain Implications

Stolen internal files frequently contain more than names and emails. They can include phone numbers, addresses, project notes, or references to family members and collaborators. Attackers combine these fragments with data from earlier breaches to build detailed profiles. Once a single handle or email is linked to your real identity, it becomes easier to locate social-media accounts, gaming profiles, or children’s online activity. This chaining effect turns one institutional breach into a persistent privacy problem that can expose your household for years.

The Gentlemen’s Publicly Known Track Record

Public reporting attributes The Gentlemen with emerging in recent years as a ransomware operation that targets organizations across Europe and beyond. The group is known for breaching mid-sized institutions, exfiltrating internal documents, and then pressuring victims through dual tactics of encryption and data leaks. Their playbook typically involves initial access through common vulnerabilities or phishing, followed by exfiltration of sensitive files and publication on dedicated leak sites if ransom demands are not met. Notable prior victims have included various public and private entities whose data appeared on the same leak platform.

What to do

• Run a DoxxScan to map every link between your emails, phone numbers, usernames, and real-world identity so you can see exactly what this claimed breach connects to.
• Rotate any password you used at ivdnt.org or related services and enable 2FA through an authenticator app rather than SMS.
• Enable continuous DoxxScan monitoring across 13.1B+ breach records and 100+ platforms so the next exposure of your information is caught and addressed in hours, not months.
• Cover the household with DoxxScan family protection that extends to dependents and children’s gaming accounts, which often become targets when credential leaks create doxxing chains.
• Let remediation specialists handle the time-consuming work of sending takedown requests to data brokers and monitoring for reappearance of your family’s details.
